rtmpdump vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

rtmpdump could be made to crash or run programs as your login if it
processed a specially crafted stream.

Software Description:
- rtmpdump: small dumper for media content streamed over the RTMP protocol

Details:

Dave McDaniel discovered that rtmpdump incorrectly handled certain
malformed streams. If a user were tricked into processing a specially
crafted stream, a remote attacker could cause rtmpdump to crash, resulting
in a denial of service, or possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
  librtmp1                        2.4+20151223.gitfa8646d-1ubuntu0.1

Ubuntu 14.04 LTS:
  librtmp0                        2.4+20121230.gitdf6c518-1ubuntu0.1

In general, a standard system update will make all the necessary changes.
